Cov yam ntxwv ntawm Peb-theem plaub-xaim Electronic Prepaid Zog Meter
(1) * Sau rau pem hauv ntej thiab thim rov qab lub zog ua haujlwm,
* Ua ke lub zog ua haujlwm (kev xaiv xaiv ntawm lub zog ua haujlwm, lossis lub zog tsis muaj zog).
* Plaub-theem txwv reactive zog, ua ke reactive zog 1 (programming xaiv ntawm forwarding reactive zog los yog inductive reactive zog), ua ke reactive zog 2 (programming xaiv ntawm forwarding reactive zog los yog capacitive reactive zog).
(2) Kev ntsuas qhov tseeb:
Lub zog ua haujlwm qib 1S: raws li IEC62052-21
Reactive zog theem 2: raws li IEC62052-23.
(3) High-precision ntsuas ntawm qhov pib tam sim no mus rau qhov siab tshaj plaws tam sim no nyob rau hauv ntau yam.
(4) Multi-rate metering: Lub zog ua haujlwm, lub zog reactive, thiab lub zog pom tseeb yog ntsuas raws li lub sijhawm ntsuas.
(5) LCD kua siv lead ua kua zaub cov ntaub ntawv, qhia lub zog kev taw qhia thiab cov lus qhia sib xws.
(6) Kev suav cov txheej txheem ntawm kev thov siab tshaj plaws. Slip lub sij hawm tuaj yeem teem caij.
(7) Kev ntsuas lub sijhawm tiag tiag, sau cia, thiab saib xyuas cov khoom siv hluav taws xob xws li voltage, tam sim no, zaus, active / reactive / pom lub zog, thiab lub zog ntawm txhua theem.
(8) Load curve recording (programmable xaiv ntawm lub sij hawm kaw, kaw cov ntaub ntawv cov khoom).
(9) Cov ntaub ntawv khov ua haujlwm. Qhov ntsuas thiab ntsuas tus nqi tuaj yeem khov txhua hnub.
(10) Cov ntaub ntawv xwm txheej thiab txuag kev ua haujlwm. Nws tuaj yeem ntes thiab sau cov xwm txheej xws li tsis muaj hluav taws xob, qhov poob tam sim no, theem tsis ua haujlwm, rov qab kev taw qhia, overcurrent, overvoltage, under-voltage, thim rov qab theem ntu, tripping, kaw, muaj zog sib nqus cuam tshuam, thiab npog qhib ntawm txhua theem.
(11) Kev tiv thaiv tub sab nyiag ua haujlwm. Tshawb xyuas thiab kaw qhov qhib tsis tau tso cai ntawm lub davhlau ya nyob twg npog.
(12) Thaum ib tus neeg theem tsis ua haujlwm lossis siv rau ob-theem lossis ib-theem hluav taws xob, lub ntsuas hluav taws xob tseem tuaj yeem ua haujlwm ib txwm thiab ntsuas tau raug.
(13) Nws muaj kev sib txuas lus kho qhov muag uas ua raws li IEC62056-21. Siv lub khoos phis tawj los nyeem cov ntaub ntawv ntsuas ncaj qha thiab siv cov txheej txheem tseem ceeb hauv ntau theem los ua haujlwm ntawm qhov chaw.
(14) Nrog RS-485 kev sib txuas lus interface.
(15) Koj tuaj yeem xaiv los hloov qhov kev sib txuas lus module thiab nthuav cov kev sib txuas lus sib txuas raws li daim ntawv thov tiag tiag. Tam sim no, nws txhawb PLC, RF, thiab GPRS.
(16) Lub ntsuas hluav taws xob hluav taws xob muaj lub zog tsis ua haujlwm.
(17) Peb-theem plaub-xaim hluav taws xob prepaid hluav taws xob ntsuas hluav taws xob tuaj yeem tso tawm hluav taws xob ntsuas pulse thiab RTC moos mem tes.
